Abstract: This Cu-Ni deposit occurs in hyperite-gabbro fades of the mid-lower part of mafic rock mass. According to industrial grade, the ores are classified into four types of high-grade Cu-Ni ores (Ⅰ), Cu-rich and Ni-poor oires (Ⅱ), low-grade ores (Ⅲ) and Ni-rich and Cu-high ores (Ⅳ). Because of complex composition, low content of associated elements of Au, Ag, Pt and Pd, small size of most precious metal grains and hardly determining the optical character of the minerals, the method of determination and quantitative analysis should be chosen in study of its occurrence.
